ASP.NET解析原始HTML到控件 [英] ASP.NET Parsing raw HTML into Controls

问题描述

是否有可能在ASP.NET中服用含有一些HTML字符串，使ASP.NET来分析它，并为我控制？例如：

 字符串rawHTML =＆LT;表＆gt;＆LT; TD＆GT;＆LT; TD＆GT;细胞＆LT; / TD＆GT;＆LT; / TR＆GT;＆LT; /表＆gt;，
HTMLTABLE表= MagicClass.ParseTable（rawHTML）;
 

我知道，这是一个坏的事情，但我在不幸的情况，这是真的，我可以实现我需要什么（我不能修改这个特别的同事的code）的唯一途径。

另外，我知道LiteralControl可以让你有在它任意的HTML控件，但不幸的是我需要让他们转换成适当的控制。

不幸的是，HTMLTABLE不支持InnerHTML属性。我需要preserve的HTML树，正是因为它是，所以我不能把它变成一个＆LT; D​​IV＆GT; 标签

感谢。

解决方案

我想你会得到最接近的是的 Page.ParseControl ，这是ASP.NET分析器。缺点是文本你的是的一个LiteralControl，因为它没有它=服务器 - 所以你会做的字符串操作事先非常点点

在otherwords：

<$p$p><$c$c>this.ParseControl(\"<table><tr><td>Cell</td></tr></table>\")

会产生：

 控制
 LiteralControl
 

，而

  this.ParseControl（＆LT;表RUNAT = \\服务器\\＆GT;＆LT; TR＆GT;＆LT; TD＆GT;细胞＆LT; / TD＆GT;＆LT; / TR＆GT;＆LT; /表＆gt;）
 

会产生：

 控制
 HTMLTABLE
  HtmlTableRow
   HtmlTableCell
    LiteralControl
 

Is it possible in ASP.NET to take a string containing some HTML and make ASP.NET to parse it and create a Control for me? For example:

string rawHTML = "<table><td><td>Cell</td></tr></table>";
HTMLTable table = MagicClass.ParseTable(rawHTML);

I know that this is a bad thing to do but I am in the unfortunate situation that this is really the only way I can achieve what I need (as I cannot modify this particular coworker's code).

Also, I know that LiteralControl allows you to have a control with arbitrary HTML in it, but unfortunately I need to have them converted to proper control.

Unfortunately, HTMLTable does not support the InnerHTML property. I need to preserve the HTML tree exactly as it is, so I cannot put it into a <div> tag.

Thanks.

解决方案

The closest I think you'll get is Page.ParseControl, which is the ASP.NET parser. The downside is that the text you have is a LiteralControl, since it doesn't have runat="server" on it - so you 'll do a very tiny bit of string manipulation beforehand.

In otherwords:

this.ParseControl("<table><tr><td>Cell</td></tr></table>")

will produce:

Control
 LiteralControl

whereas:

this.ParseControl("<table runat=\"server\"><tr><td>Cell</td></tr></table>")

will produce:

Control
 HtmlTable
  HtmlTableRow
   HtmlTableCell
    LiteralControl
